Search External Avro Objects in Salesforce Connect

CData Connect Server, enables you to access Avro data from cloud-based applications like the Salesforce console and mobile applications like the Salesforce1 Mobile App. In this article, you will use CData Connect Server and Salesforce Connect to access external Avro objects alongside standard Salesforce objects.

Configuring Connect Server

To work with live Avro data in Salesforce Connect, we need to connect to Avro from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Avro data.

Add a Connect Server User

Create a User to connect to Avro from Reveal through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to Avro from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "Avro" from Available Data Sources
3. Enter the necessary authentication properties to connect to Avro.
   
   Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.
4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Avro OData Endpoints in Connect Server

After connecting to Avro, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the Avro database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the table definition to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.
